Characterizing bipartite distance-regularized graphs with vertices of eccentricity 4
Blas Fernández, Marija Maksimović, Sanja Rukavina
The characterization of bipartite distance-regularized graphs, where some vertices have eccentricity less than four, in terms of the incidence structures of which they are incidenc…
